Impossible to add negative value on iOS keyboard

As per picture, iOS detects a numeric field, correct, and shows a keyboard with numbers but without negative sign. It’s impossible to write a minus - there on iOS (well: I have been using copy paste from other apps…).

If there is not an numeric keyboard with negative sign available, it’s easier to simply allow a normal keyboard. (Or add an invert +/- button by side to invert any value)

There was an issue raised for this in 2024. But it went stale.

You will have to open a new issue there.
